Wallhead is grounded in England and unable to fly because of volcanic ash that’s plagued European air travel.

Bellator 15 takes place April 22 at Mohegan Sun Arena in Uncasville, Conn.

As with all Bellator shows, Bellator 15 airs live on FOX Sports Net (check local listings to assure the event isn’t preempted), and highlight packages air Saturday on NBC, Telemundo and mun2.

Thomas, a former UFC fighter, saw his tournament hopes and a shot at $100,000 dashed when opponent and U.S. Olympian/NCAA Division I national wrestling champion Ben Askren applied a guillotine choke midway through their bout. An audible grunt from Thomas prompted the referee to halt the bout and award Askren a technical submission victory, though the fighter never tapped out.

Thomas and his corner immediately protested the stoppage to no avail.

“While I am very disappointed that Jim won’t be able to make it to the U.S. this week, at least some good comes out of this situation as Ryan will get the opportunity to step back into our welterweight tournament,” Bellator founder and CEO Bjorn Rebney stated. “After the fight last Thursday, I promised Ryan that he would be our first alternate for the tournament and, based on a natural disaster, his opportunity came much sooner than anyone would have guessed. Ryan and Ben Askren were locked in a tough fight last week that was ended, somewhat controversially, by the referee. While I respect that decision, I am pleased that this opportunity has presented itself for Ryan.”

He now returns from six days’ rest to meet McClintock, a member of Arizona Combat Sports who’s posted six first-round victories in six career fights. He competed for a variety of organizations, including Rage in the Cage and Total Combat, and most recently scored a first-round TKO victory over Beau Baker (7-2 at the time) in October.

Wallhead was one of the tourney’s earlier favorites. The Cage Warriors and M-1 Challenge vet was set to enter Bellator with a six-fight win streak and 10 wins in his past 11 fights.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
